Which of the following is a common character set used for representing text in Linux environments?

The answer pertains to the ASCII (American Standard Code for Information Interchange) character set, which is widely used in Linux environments. ASCII is a 7-bit character set that defines 128 characters, which include standard letters, digits, punctuation marks, and control characters. Its simplicity and compatibility make it a foundational text encoding standard in computing, particularly in early computing systems and continues to be supported in modern systems as well.

While UTF-16 and UTF-32 are also character encoding systems that support a broader set of characters, including those needed for multiple languages and special symbols, they require more bits to represent each character, making them less common for basic text processing in standard Linux environments where ASCII suffices. Windows-1252 is a single-byte character encoding of the Latin alphabet that is specific to Windows and while it is used, it is not as universally applicable in Linux as ASCII, which is compatible across different systems and tools. Thus, ASCII remains the most common choice in Linux for text representation.
